small sampling of the many projects in which the Hawaiian SunGuard
Waterproof Membrane was successfully installed. |
| |
| BEFORE |
AFTER |
 |
|
This
recent Brai style flat roof had many leaks due to the roof seams that
kept coming undone in the high heat.
|
|
|
 |
| After our Full Fabric Reinforced Roof was
put in place there were no leaks. The ponding water here is no match
for our HSG which contains the miracle polymer "LIpaCryl." It resists
any ponding water which will evaporate within 48 hours of no rain. |

|
| |
| |
| BEFORE |
AFTER |
 |
| Years of neglect and patchwork repairs had resulted in
55,000 square feet of roofing problems. |
|
|
 |
| With reinforching fabric and coated ducts this roof is
cool, watertight, and guaranteed for 10 years. |

| BEFORE |
AFTER |
 |
This 16-story Waikiki Hotel had a pitch and gravel roof
that leaked from everywhere.
A lot of mechanical equipment, lines, and penetrations made this
building a challenge for conventional materials. |
|
|
 |
With all of the gravel removed from the roof, epoxy
primer was applied to the roof deck and high-tensile fabric was
embedded in the foundation coat and two topcoats made this roof as good
as new.
|
|
|
|
|
|
| |
| |
| BEFORE |
AFTER |
 |
| This low-slope shingle roof had leaks around almost all
of the penetrations (vents, skylights, etc.) |
|
|
 |
| Sealing all of the penetrations and reinforcing with
fabric made this leaky roof in Kaneohe watertight. |
|
|

| BEFORE |
AFTER |
 |
| Take a look at this old, EPDM (rubber) roof near Sand
Island. Imagine how HOT it must have been inside this building. |
|
|
 |
Hawaiian SunGuard fluid applied membrane over EPDM. How
cool does this old leaky, black roof look now?

|
|
|
| |
| |
| BEFORE |
AFTER |
 |
| This mechanical storage building had worn-out capsheet
and the temperature was unbearable. |
|
|
 |
| The surface has been restored, repair people can
comfortably work inside and it looks great. |
|

| BEFORE |
AFTER |
 |
| LEAKS, LEAKS, and MORE LEAKS. Halawa Valley metal
roof could not keep tenants dry. |
|
|
 |
| Using fabric in the foundation coat on seams and
penetrations guaranteed this roof for 10 years. |
|

|
|
| |
| |
| BEFORE |
AFTER |
 |
| No leaks at this home in Kalihi, just the scorching sun
forcing the homeowner to run AC all day. |
|
|
 |
| Problem solved with 4 gallons/100 sq. ft. of Hawaiian
SunGuard coating: 9°cooler inside. |

Numerous leaks originating from the seams of the
rolled-roofing and parapet walls on this building in Kaneohe.

 |
| This leaky roof had two types of materials that didn't
match and couldn't keep out the rain. |

| Tinted to match the original color, Hawaiian SunGuard
waterproof membrane made everything watertight. |

Classroom Challenge |

Location: Honolulu
Waldorf School
Date: 10/04/2006 at 1:36 pm
Weather: Sunny / Light Trades
Roof: Light Brown Shingles |
| |
| With excellent
ventilation, room temperatures felt comfortable on the day we did our
test. However, teachers and staff agreed that without trade winds the
rooms get very hot and stuffy, which is why they initially called us.
The uncoated roof heated to 150.2 degrees in October (not even the
hottest part of the year.) The adjacent Hawaiian SunGuard roof
remained a relatively cool 88 degrees. More surprising were the results
on the flat rolled-roofing. Even on the newly installed white cap
sheet, surface temperatures reached 136 degrees (bottom right photo).
On the underside, Hawaiian SunGuard was responsible for lowering
ceiling temperatures by an impressive 16.9 degrees. This is important
because ceilings will radiate heat and increase the interior
temperature. |
| |
|
|
| |
 |
| |
 |
| |
 |
| Using an infrared heat gun, the ceiling temperature at
Barber's Point Elementary averaged 89.8° before Hawaiian SunGuard was
applied. The ceiling temperature measured 69.4° after Hawaiian SunGuard
was applied. |

Location: Barber’s Point
Elementary
Date: 10/10/2006 at 12:45 pm
Weather: Sunny
Roof: Brown Cap Sheet
In the heart of Oahu’s Ewa Plain, Barber’s Point Elementary gets baked
by the sun. The combination of brown cap sheet and pitch / gravel roofs
makes for a giant heat trap. Hawaiian SunGuard Installed SunGuard Temp
Brown Cap Sheet With a thick concrete slab roof deck over most
classrooms, we were not expecting to see the dramatic results normally
observed on open-beam ceilings. However, the results were impressive.
The temperature difference between the untreated and coated surfaces
was an astonishing 70 degrees. Even more surprising was the temperature
on the underside of the roofs. The ceiling temperature of the uncoated
classroom was almost 20 degrees hotter the Hawaiian SunGuard cool roof. |

Letter to the Editor

The Honolulu Advertiser
"COOL ROOF" PROGRAM
SMARTER FOR SCHOOLS
The headlines "Beach
Erosion 'Widespread'" and "It's Like Studying in a Sauna" (August 6)
could together be titled, "Hawai'i shooting itself in the foot."
The cause of beach erosion
is the rising ocean level, which is caused by global warming. Global
warming plus hot-box classrooms create sweat. The "solution" is air
conditioning, which burns more oil for electricity, which causes global
warming, which raises ocean levels and causes higher land temperatures,
which necessitates more AC. It's a devilish downward spiral.
Air conditioning
classrooms is like putting ice cubes in ovens. Many older classrooms
were inadvertently designed to collect heat. A group of selfless
businessmen have donated time and materials to create "cool roofs" at
Waipahu High School. Cool rooms reflect, rather than absorb the sun's
heat. The result is classrooms that feel a good 8 degrees cooler.
Spending tax dollars to AC
old hot boxes is like subsidizing state cars to run on flat tires. Each
school will spend millions to install AC and the electricity cost will
rise by $87 per student per year, year after year after year. Isn't
there a textbook and computer shortage?
Finally, AC'd classrooms
are often boarded up. Scientific tests show that students with good
outdoor views perform 20 percent better than those with poor views. The
new DOE leadership is committed to green school design and that's
great. Meanwhile cool roofs plus super-efficient ceiling fans will
dramatically cool down most existing classrooms. Tax dollars for cool
roofs will not only cool down classrooms but also contribute to a
cooler earth and stabilized ocean levels.
